Tips

Questions to ask when assessing your collection:

  • Community Needs
    • Is the collection meeting the needs and interests of the community?
    • Are there unmet information needs in the community that the library could provide? For example: health, social services, sexual/reproductive services, employment services, etc.
    • Keep in mind that circulation data may not tell the whole story about community needs.
  • Collection Standards
    • Is the collection meeting the standards outlined in the library’s collection development policy?
    • Is the collection meeting the standards outlined by MORE?
  • Age of Collection
    • How old/current is the collection?
    • How old/current are specific areas of the collection that may age more quickly (for example: non-fiction, Dewey areas)?
    • See shelf-life guidelines in the CREW Manual and compare age of collection statistics to these guidelines.
  • Collection Usage:
    • How is the collection currently being used?
    • How has collection use changed over time?
    • Would the collection benefit from updating/weeding/promotion to increase usage?

Relative Use equation

Relative Use is the ratio of the percentage of a collection’s circulation vs. the percentage of holdings in that particular area.

  • This type of analysis can be broken down into separate library sections or locations
  • Goal is a 1:1 ratio
  • If relative use is greater than 1, it indicates that circulation is higher than holdings, and we should consider increasing the size of the collection
  • If relative use is less than 1, it indicates that circulation is lower than holdings, and we should consider weeding the collection or promoting it to encourage better circulation
  • If relative use is near or exactly 1, this indicates that we are adequately adding to and weeding the collection
